How to play
Missing part
Choose the number needed to complete the target. Pictures make each group visible.
Bond explorer
Adjust both groups, save every correct pair and watch the collection fill.
Made for your child
Use the target their class is practising and replace the starter stars with footballs, animals, instruments or anything they recognise.
Keep it supportive: This is a home practice game, not an assessment. A grown-up should choose a suitable target and help with counting when needed.

Build me a mobile-friendly number-bond game as one standalone HTML file. Let a parent choose a target number from 2 to 30 and a favourite emoji. Include a missing-part game with visible counters and multiple-choice answers, plus an explorer where a child adjusts two groups and collects every unique pair that makes the target. Track score, streak and best streak, save settings and progress only in local browser storage, explain privacy accurately and include a supportive grown-up note.
